Recently, the marine leisure industry has begun to make a mark on the growth engines of the Korean economy. Hence, various government research projects are in progress to catch up with the fundamental yacht technologies of advanced countries. Research on the integrated management technologies of sail yachts is carried out as a part of those projects. Work Breakdown Structure (WBS) is a basic architecture for robust and high-level management systems. In this paper, we suggest a product-oriented Yacht Work Breakdown Structure (YWBS). General WBS has a drawback in that it can only follow the targeted purpose, but YWBS allows for a generic WBS approach. This concept allows us to apply WBS to multi-purpose uses. The YWBS is used as an infrastructure in information management and for data relationships in sail yacht management systems. YWBS is designed and managed by a web application, and the system is implemented with a website as a user interface. This application has not only a design function, but also a data transfer function that is based on the Microsoft Silverlight platform, a kind of Rich Internet Application (RIA) technology. Using this application, YWBS designers can communicate with the management system without added tasks like as uploading and updating.

As digital technologies have strongly impacted the whole social aspects, so museum recently emerging as an alternative or supplementary learning environment to school, after active adoption to the technologies, gave birth to museum websites called 'Virtual Museums' which, then, result in enhancing the educational roles and functions of physical museum. In this context, this study aimed to review the process of how virtual museum has been developed in terms of its educational roles and characteristics in accordance with the evolutionary development of web. Especially, the analysis of the status quo of the current virtual museums in both Korea and overseas presented specific aspects of the educational elements and roles embedded in virtual museum which have been emphasized in many related research and studies. The categories of the roles of the virtual museum, as a result, were classified into 'digital archive,' 'learning resources,' and 'communigy,' each of which were, then, further elaborated for its individual educational uses. Eventually this study purposed to expand the public awareness and knowledge of virtual museum as the alternative online learning environments needed in the 21st century.

Recently, as the technology has been blended with IT, BT or NT and technology in each field has been developed progressively with the people's needs for a healthy and abundance life. In the medical service field as well, related technologies such as medical equipment, medical information system, or medical business application have come to be diversified and advanced. However, most of these medical technologies are being developed independently without an interaction with other medical institutions or related companies, which causes many problems in the integration or interchangeability of them. This paper is intended to solve the problems generated during a direct information sharing between the functional interfaces of the present healthcare information sharing system. This paper develops a repository between the interfaces, which can save all the healthcare information from the institutions, and convert and publish it in various forms of document. In other words, recently HL7 protocol has been used for sharing the healthcare information in order to save the information in XML format, and develops the H-DISS(Healthcare-Documents Integrated Sharing System), a repository to manage and publish the saved document.

This study is aimed at the development of ubiquitous based road disaster management system. The fundamental technologies used for developing this system are classified into three modules - wireless internet communication module, mobile module and server module. These fundamental technologies can be used not only for developing road disaster management system but also for developing various mobile or ubiquitous systems. With this system, workers can download many DB (Digital map, Attribute information etc.) from server to the field in realtime. The accuracy and objectivity of the DB could be improved with these informations collected at fields because these data can be used as basic data for road disaster information collection. Because in the web based server module - Web based Road Disaster Management System (URDMS) - field disaster information was showed link up with exist DB on road by absolute coordinate, the decision making with all of the field information was made and it sent to a field staff in realtime. The problems of current road disaster management rule ran be solved by this URDMS.

As cyber threats have been increased over the Internet, the invasions of personal information are constantly occurring. A malicious user can access the Web site as a normal user using leaked personal information and does illegal activities. This paper proposes an effective method which authenticates a genuine user with real-time. The method use the user's profile which is a record of user's behavior created by Membership Analysis(MA) and Markov Chain Model(MCM). In addition to, user's profile is augmented by a Time Weight(TW) which reflects the user's tendency. This method can detect a malicious user who camouflage normal user. Even if it is a genuine user, it can be determined as an abnomal user if the user acts beyond the record profile. The result of experiment showed a high accuracy, 96%, for the correct user.

Advancing geo-spatial web technologies and their applications require compatible and interoperable heterogeneous browsers and platforms. Reduction of common or supporting components for web-based system development is also necessary. If properly understood and applied, OGC-based standards can be utilized as effective solutions for these problems. Thus, OGC standards are central to the design and development of web-based geo-spatial systems, and are particularly applicable to web services, which contain data processing modules. However, the application for OGC WPS 2.0 is at an early stage as compared with other OGC standards; thus, this study describes a test implementation of a web-based geo-spatial processing system with OGC WPS 2.0 focused on asynchronous processing functionality. While a binary thresholding algorithm was tested in this system, further experiments with other processing modules can be performed on requests for many types of processing from multiple users. The client system of the implemented product was based on open sources such as jQuery and OpenLayers, and server-side running on Spring framework also used various types of open sources such as ZOO project, and GeoServer. The results of geo-spatial image processing by this system implies further applicability and extensibility of OGC WPS 2.0 on user interfaces for practical applications.
